Involved in cilium assembly; cilium movement involved in cell motility; and spermatogenesis. Acts upstream of or within cerebrospinal fluid circulation; motile cilium assembly; and mucociliary clearance. Predicted to be located in cilium; cytoplasm; and cytoskeleton. Orthologous to human CFAP54 (cilia and flagella associated protein 54). [provided by Alliance of Genome Resources, Apr 2022]
